Powertrain & Engine Architecture
The heart of this RAM 2500/3500 variant is the 6.7-liter Cummins inline-six diesel engine, designated with the ETJ code. This engine represented a significant leap forward in diesel technology for the heavy-duty truck market. It utilizes a common-rail direct fuel injection system, delivering fuel at extremely high pressures for improved combustion efficiency and reduced emissions. The engine is turbocharged and intercooled, enhancing power output and minimizing turbo lag. The 24-valve cylinder head features two valves per cylinder, contributing to efficient gas exchange. The six-speed automatic transmission, sourced from Allison, was specifically calibrated to handle the substantial torque output of the Cummins engine. This transmission featured electronically controlled shifting and a tow/haul mode for optimized performance when towing heavy loads.
Driving Characteristics
The 350 horsepower and 881 lb-ft of torque delivered by this powertrain configuration provided ample power for demanding tasks. While not as quick as the higher-output Cummins variants, the 350 hp version offered a more relaxed and manageable driving experience. The automatic transmission, while smooth, wasn’t particularly sporty. Gear ratios were optimized for towing and hauling, resulting in relatively conservative shift points. In real-world conditions, this truck excelled at tasks like towing large trailers, hauling heavy payloads, and navigating challenging terrain. The 4×4 system provided excellent traction in off-road situations. Compared to the manual transmission equipped models, the automatic offered greater convenience, especially in stop-and-go traffic, but at the expense of some driver control and fuel efficiency.
Equipment & Trim Levels
The 2500/3500 Crew Cab I with the 6.7L Cummins and automatic transmission was typically offered in mid-range trim levels, such as the SLT or Laramie. Standard features generally included air conditioning, power windows and locks, a basic audio system, and cloth upholstery. The Crew Cab configuration provided spacious seating for up to six passengers. Optional extras included leather upholstery, a premium sound system, navigation, heated seats, and various towing packages. The interior design was functional and durable, prioritizing practicality over luxury.
Chassis & Braking
The RAM 2500/3500 featured a robust chassis designed to withstand heavy loads and demanding use. The front suspension utilized an independent multi-link setup for improved ride quality and handling. The rear suspension employed a traditional leaf spring design, providing excellent load-carrying capacity. Braking duties were handled by disc brakes on all four wheels, equipped with an Anti-lock Braking System (ABS) for enhanced safety. The braking system was appropriately sized to handle the truck’s weight and towing capacity. Stabilizer bars were included to reduce body roll during cornering.
Market Reception & Comparison
The RAM 2500/3500 with the 6.7L Cummins and automatic transmission was generally well-received by critics and consumers alike. It was praised for its powerful engine, comfortable ride, and impressive towing capacity. Fuel economy, while typical for a heavy-duty diesel truck, was a point of consideration. Compared to the higher-output Cummins variants, this 350 hp version offered a more affordable entry point into the heavy-duty truck market. It also provided a more refined driving experience compared to the base gasoline engines. Reliability was generally good, although diesel engines require diligent maintenance to ensure longevity.
Legacy
The 6.7-liter Cummins engine has become legendary for its durability and longevity. This particular variant, while not the most powerful, has proven to be a reliable workhorse for many owners. In the used car market, these trucks continue to hold their value, particularly those that have been well-maintained. The combination of a powerful diesel engine, a capable automatic transmission, and a spacious Crew Cab configuration makes this RAM 2500/3500 a popular choice for buyers seeking a versatile and dependable heavy-duty pickup truck. Common maintenance items include regular oil changes, fuel filter replacements, and inspection of the cooling system. With proper care, these trucks can easily exceed 200,000 miles of service.
